The ratio of length to breadth of a rectangle is 8:5.
When the length and breadth of the rectangle is increased by 22% and decreased by 30% respectively, then its perimeter becomes 663 cm. Find the original area (in cm2) of the rectangle.Solution
Let the original length and breadth of the rectangle be 8x cm and 5x cm, respectively According to the question, 2 × {(1.22 × 8x) + (0.7 × 5x)} = 663 Or, 9.76x + 3.5x = 331.5 Or, x = 331.5/13.26 = 25 Therefore, original area of the rectangle = 8x × 5x = 40x2 = 25000 cm2
